This is a genuine OEM sourced replacement part used on gas trimmers/edgers. The purpose of this part is to mix air and gas before the fuel mix goes to the engine.
If the engine won't start and the tank is full of fresh fuel, test the carburetor by removing the air filter and pouring about a teaspoon of fuel into the carburetor. Pull the starter rope. If the engine starts and then quickly dies, the carburetor is likely the problem.
This is a metal body carburetor, it is sold individually. This assembly includes fuel lines, primer bulb. You will need a screwdriver to perform this repair.

1.) Removed the 4 - 5 top cover screws
2.) Removed the air breather cover, filter and filter grate, and assembly. See the spacers in the housing for the long bolts put them back, a big help to have.
3.) Removed the carburetor.
4.) Disconnected the throttle connection from the carburetor.
5.) Lift and discounted the throttle cable securement from the body of the motor, use two standard screwdrivers to push in on both sides of the holder, it just lifts off and out of the way.
6.) Remove the carburetor gasket, big cardboard piece. Remember to tuck in under the plastic housing when reinstalling
7.) Remove and reinstall the spark plug if needed, did they come pre-set, the carb too.
8.) Re-install in reverse.
9.) Change the oil while you are there. Do not overfill or it will run out of the air breather assembly.
10.) The power bit starter is great, all small engines should have one of these. A standard square bit, I bet would work too.
